Index -CNC-Plus Germany. $20 Drag Knife. I have come up with two drag knife designs that can be made for about $20.

$20 Drag Knife

Both designs allow mounting in a 1/2" router collet. The first design is based on the Roland Blade Holder, and is spring-loaded to allow for slight surface variations - this one would be used for thin materials like Vinyl. Adaptation d'un porte lame Roland pour faire de la découpe vinyl avec une CNC. Les enseignistes connaissent bien la découpe vinyl qui leur permet de faire de nombreux marquages.

Adaptation d'un porte lame Roland pour faire de la découpe vinyl avec une CNC

Le principe est simple : Une feuille de vinyle autocollante est découpée à l'aide d'un plotter de découpe spécialisé, et l'opération est répétée pour chacune des couleurs nécessaires. Les découpes inutiles sont ensuite 'pelées', et collées à l'envers sur une feuille qui va servir de support pour le transfert sur le support final. Le support final sera ensuite nettoyé et humidifié avec un agent mouillant (eau + produit vaisselle...), qui facilitera le repositionnement de l'autocollant, puis lorsque tout est en place, il suffit de chasser les bulles (et l'eau) avec une raclette. Certes, ces machines sont peu couteuses (à partir de quelque centaines d'euros), mais leur achat n'est envisageable que si l'utilisation est récurrente.

Woodworking for engineers. Calibrating Feeds and Speeds with Carbide Microtools. The first question that most people ask when using carbide mini and micro tools to cut wood (and other soft materials) for the first time, is, "What are the best speeds and feeds?

Calibrating Feeds and Speeds with Carbide Microtools

". What they really want to know is, "How fast I can cut without breaking a bit? What are the optimum cutting conditions with my equipment? " If you are primarliy cutting metal, in most cases, the process of selecting the proper speed (RPM) and feed-rate is relatively straightforward. If you are cutting woods or plastics, the world is not so kind.

Nonetheless, it is possible to arrive at an optimum combination of speed and feed reliably and repeatably without experiencing too much brain-death. The following discussion assumes that: In any particular material, tool performance, and longevity are primarily influenced by: Rabbit Laser USA. Torsion Box Table Initial module. Torsion Box Table Initial module One is required for each table.

This assembly is used to mount the chain ends (overlap designed at the ends). This is also a great option as a standalone table top/workbench if stiffness is needed. Included: Two top and bottom ends Supporting ribs Provides 33.5625" length 112 screws (1/4"-1-1/2") and cross dowels 56 washers for underside layer Actual rib count and lengths will depend on final options purchased according to the staggering combinations.

3D Printed Raspberry Pi Compatible Open-Source Humanoid Robot

Poppy has been designed as a robotic platform for research, art and education. It is a open-source project and its aim is to be as simple, flexible and affordable to the masses as is reasonably practical. “Poppy was initially made for our research project about understanding biped locomotion, and full-body physical and social interaction in robots and humans.” Poppy is lightweight at 3.5kg, resulting in lower power-to-motion necessity, but still with enough juice to do a wide range of tasks. Although the robot is light, this does not automatically point to fragility. To give Poppy more agility and stability during motion, bio-inspired morphology has been incorporated into the robots design including, bended legs, a multi-articulated trunk and a soft body. Fully assembled Poppy stands at 84cm, and take’s about two days to build.
